Hi there
I am have limited knowledge of Mikrotik so be gentle.
The scenario… I have a client with a HO and some remote sites. The PBX resides at HO and i can register a voip phone from my remote office but not from their remote site. The remote site has a Mikrotik L009UiGS-2HaxD. This was not configured by me but the users can break out with their devices.
The issue i am having is the registration fails. i have disabled the SIP in services. But i think it could be the firewall rules?
Any suggestions?
Thanks
